when is blood pressure too low

Blood pressure is generally considered too low when it is below 90/60 mm Hg. This condition is called hypotension. However, low blood pressure is only considered problematic if it causes symptoms or is linked to an underlying health issue. Symptoms that might indicate blood pressure is too low include dizziness, fainting, fatigue, blurred vision, trouble concentrating, and in severe cases, symptoms of shock such as confusion, cold and clammy skin, rapid shallow breathing, and a weak, rapid pulse. A sudden drop in blood pressure by about 20 mm Hg can cause noticeable symptoms like dizziness or fainting. Low blood pressure can occur due to various causes including dehydration, heart problems, certain medications, hormone-related diseases, severe infection, blood loss, and nutritional deficiencies. For some people, low blood pressure without symptoms may not require treatment but should be monitored. In summary, blood pressure readings lower than 90/60 mm Hg are typically considered low, and it is considered "too low" when accompanied by symptoms or caused by serious health conditions that require medical attention.
